ESP8266-14 is a WIFI-MCU communication / control module, the built-in WIFI
IC communication ESP8266 and STM8003 microcontroller, can be widely used in
smart home and the Internet of things, for the user's physical devices
connected to the Wi-Fi wireless network, Internet or local area network
communication, real networking capabilities.
The module built a powerful STM8003 chip, all the pins are all connected to
the serial port and ESP8266 serial port connected, the user can write STM8
program, through the AT command to control the ESP8266 to achieve the vast
majority of smart home and WIFI features.
